1 UNITED STATES PATENT OFF-ICE.

JAMES MAOPHAIL, OF ROCKFORD, ILLINOIS.

MOWER.

SPECIFICATION forming part of Letters Patent No. 423,435, dated March 18, 1890.

Application filed December 4, 1889. Serial No. 332,594. (No model.)

To all whmn it may concern.-

Be it known that I, JAMES MACPHAIL, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Mowers, of which the following is a specification. I

My invention relates to means for raising and lowering the cutter-bars of mowers; and

ted lines the parts and movements necessary to raise the cutter-bar by means of the foot lifting-lever,'the latter indicating in like manner the parts and movements required to raise the cutter-bar by means of the hand lifting-lever or the hand lifting-lever and foot lifting-lever in conjunction.

Like letters of reference indicate corresponding parts throughout the several views.

A A A are respectively an axle, the Wheels,

and frame of a mower of the usual or any suitable form and construction.

A A are horizontal bearings, preferably integral with and mounted 011 the mower-frame A forward of the main axle.

B is the inner shoe of a mower.

B is a finger-bar fragmentalsecured thereto.

C is a liftin -cam provided at its rear portion with the segment-gear O, the backwardly, downwardly, and obliquely extending arm 0 and at its upper portion with the upwardlyextending arm 0 and said cam O is mounted on the bearing A D is afoot lifting-lever provided at its lower end with the counterpart segment-gear D, meshing with the segment-gear C of the lifting-cam C, and mounted on the bearing A.

E is a hand lifting-lever mounted on the frame of the mower.

F is a chain connecting the free end of the arm 0 of the lifting-cam O with the hand lift- G is a chain connecting the lifting-cam C with the finger-bar B.

H is an auxiliary spring extending from the free end of the arm (J of the lifting-cam O to the bracket I, which is fast to the tongue of the machine. Obviously it is not material what particular form of fastening is used where I have employed the bracket I. The

function of the spring H is to assist the 0per-, ator in raising and lowering the finger-bar B.

\Vhenever it is desired to partially raise the finger-bar to pass obstructions or turn corners in mowing, the operator will press his cam provided at its rear portion with the seg- 7 5 mentgear 0 and the backwardly, downwardly, and obliquely extending arm 0 and mounted on the bearing A the foot liftinglever providedat its lower end with the segment-gear D], meshing with the segment-gear 8 0 of the lifting-cam and mounted 011 the bearing A the connection between the finger-bar and lifting-cam, the auxiliary spring extending from the lifting-cam to the bracket on the tongue of the machine, and the necessary parts for operatively connecting the same together and with the machine, substantially as and for the purpose specified.

2. In combination, the mower-frame having bearings A A mounted thereon forward of 0 the main axle, the finger-bar, the lifting-cam provided with the segment-gear C and the backwardly, downwardly, and obliquely extending arm 0 at its upper portion, with the upwardly-extending arm G and mounted on the bearing A the foot lifting-lever provided with the counterpart segment-gear D and mounted on the bearing A the connection between the finger-bar and lifting-cam, the auxiliary spring connecting the lifting-cam with the bracket on the tongue of the machine, the hand lifting-lever mounted on the machineframe, and the chain for connecting the hand lifting-lever with the free end of the arm 0 of the lifting cam, when all of said parts are adapted and arranged to operate substantially as and-for the purpose specified.

3. In combination, the mower-frame provided with bearings A A the lifting-cam C, mounted on the hearing A and provided with the segment-gear C, the foot lifting-lever D, mounted on the bearing A and provided With the segment-gear D, the auxiliary spring H, connecting the lifting-cam C With the fastwith the segment-gear C, the foot lifting-1ever D, mounted on the hearing A and provided with the segment-gear D, auxiliary spring H, connecting; the lifting-cam O with the bracket on the tongue of the machine, the hand lifting-lever E, mounted on the mowerframe, the chain F, connecting the lifting-v cam G with the hand lifting-lever E, the finger-bar B, and the chain G, connecting the same With the lifting-cam 0, all of said parts being adapted and arranged to operate substantially as and for the purpose specified.
